| With developments in molecular biology, biologists have powerful new tools to determine the relatedness of specimens found at different locations. Studies of chromosomes and gene sequences have helped identify Cockrum's Gray Shrew and several other species as being distinct from Notiosorex crawfordi, even where their ranges appear to overlap.
